Click2Pick
This small mod completely changes the item pickup system in Minecraft, making the process more realistic and controlled. Instead of automatically collecting everything, you can choose specific items you want to pick up.
Simply aim at the desired item on the ground and right-click - the item will go into your inventory. The name of the selected object will appear above your crosshair:

Additionally, the mod changes the visual display of dropped items - they now lie on the surface instead of floating in the air, adding realism to the game without complex physics calculations.
If you need to quickly collect all items around you, just hold Shift (sneak) - in this mode, the standard auto-pickup works:

This system not only enhances immersion in the game world but also solves one of Minecraft's main problems - constant inventory clutter with unnecessary items.
